npub1sflk8glpsgdpsuu8lv97fynz8hxg9xct2zcp63aql99cdr3mvdtsqwgczt (npub1sfl…gczt) If they replaced just the physical battery, they also need to reset the internal "gas gauge" chip. Actually measuring the level of a battery is impossible for tl;dr, so a little chip measures how much goes in and out. Over time, it learns the capacity of the battery and has to adjust its memory when the batt reaches emergency voltage level. For a new battery, fully charge and then fully discharge (until it emergency shuts down) to teach the chip the new size.
